Below are the most common (but not the only) causes of noise and vibration problems:

- Tire / wheel assembly is out of balance

- No hub rings on aftermarket wheels

- Incorrect mounting hardware for aftermarket wheels

- Tire is poorly seated on the rim

- Irregular tire wear

- Out of round rim

- Out of round tire

Do not ignore apparent impacts, pulling, or vibration. This could be an indicator of tire damage as much as mechanical problems that should be inspected by a professional. If there is a problem with your tires and the way they have been installed they will most likely begin to shake and vibrate your vehicle at between 50 and 65 mph.
